Abstract
This document describes the functional specification
and the definition of the ENUM NAPTR record, for IFax
service. IFax is "Facsimile using Internet Mail". For
this use, the DNS returns the email address of the
referenced IFax system. This mechanism allows email-based
fax communication to use telephone numbers, rather than
requiring that the sender already know the recipient
email address.
1. Functional Specification
An IFax client makes an [ENUMbis] DNS query, using the target
system's telephone number. The returned NAPTR record
specifies an email address that is to be used for reaching
the target system. The email address is then used in
accordance with "Simple Mode of Facsimile using Internet
Mail" [RFC2305] or "Extended Facsimile using Internet
Mail" [RFC2532]. "Full Mode Fax Profile for Internet Mail"
is applied when it is approved as an Internet standards-track
specification.
2. IFax service Registration
Service Name : "ifax"
Type: "ifax"
Subtype: "mailto"
URI Scheme: "mailto"
The URI Scheme is "mailto" because facsimile using
Internet Mail is a profile for standard Internet mail and
uses standard Internet mail addressing.
Functional Specification: see section 1
Security Considerations: see section 3
Intended usage: COMMON

3. Security Consideration The Security Considerations section of [RFC2305] and
[RFC2532] applies to this document. In addition, note
that DNS records are public. Therefore the mapping between
a telephone number and a specific email address is public.
4. Example The following is an example of the use of IFax service
in a NAPTR record.
$ORIGIN 4.3.2.1.6.7.9.8.6.4.e164.arpa
IN NAPTR 10 10 "u" "E2U+ifax:mailto" "!^.*$!mailto:toyo@ifax.com!"
5. IANA CONSIDERATIONS
This specification creates a DNS NAPTR registration, according to
the terms specified in [ENUMbis]
The registration details are contained in section 2,
"Fax service Registration", above.
